I ran this oil 1156 miles this year I have seen no advantage of using this oil. They told me my power valves would stay clean and my sled would not smoke, WRONG. This oil is so thin it is like crisco oil that you would cook with, I had to turn my oil pump down 3.5 turns to allow for the difference and get a 50:1 ratio. Did you notice they are re-jetting on thier dyno charts and giving the cretit to thier oil. I have called and e-mailed them many times and they finally told me this morning they could'nt help me......
